William Katipa

William Wii Katipa is a New Zealand rapist, prison escapee and Black Power gang member currently serving two preventative detention sentences, one for rape on the outside and one for prison rape.

Katipa was raised as "the son of drug addicts who himself seemed constantly stoned." In 1991, he was sentenced to prison for armed robbery.

In 2006 a complaint of prison rape was made against Katipa, but it did not progress due to lack of evidence. In 2015 a separate compliant lead to a third complaint being made. After a widely watched trial, Katipa was convicted of 14 charges against the three complainants.

Katipa's actions and those of Stephen Mark Gotty, a rapist with more than 145 convictions, led to a review of the double-bunking policy by the Corrections Department.
